      Deprecated the separate handle on rectangular tx_size in var_tx · fe45b216
      Jingning Han authored
      The recursive transform block partitioning system naturally supports
      the use of rectangular transform block size. Hence there is no need
      to make a separate coding route for the rectangular transform block
      size support there.

      This commit adds an experiment to interleave the coding of transform
      coefficients from YUV planes.  The experiment can be enabled at config
      time by --enable-coef-interleave.

      Fix clpf + ext_partition and dering + ext_partition · 9739f365
      David Barker authored
      In both cases, the data to be signalled (for clpf/dering) is
      stored at the topmost superblock level, but previously this data
      would not be signalled for 128x128 superblocks.
      
      For dering, it was also assumed that all superblocks were of the
      maximum possible size. When ext_partition was enabled and we
      chose to use a 64x64 superblock, this resulted in an out-of-bounds
      access to cm->mi_grid_visible, leading to a segfault.

      Fix the bug that PVQ commit broke dering · 48f84dbd
      Yushin Cho authored
      Since PVQ's max block size equals to the max transform size,
      daala's definition of OD_BSIZE_MAX was changed from 5 down to 4 to
      use AV1's max trasform size 32x32. However, dering also uses
      OD_BSIZE_MAX and assumes its value is 5, which caused dering
      not working.

      New experiment: Perceptual Vector Quantization from Daala · 77bba8d3
      Yushin Cho authored
      PVQ replaces the scalar quantizer and coefficient coding with a new
      design originally developed in Daala. It currently depends on the
      Daala entropy coder although it could be adapted to work with another
      entropy coder if needed:
      ./configure --enable-experimental --enable-daala_ec --enable-pvq
